TECHNICAL FIELD OF THE DISCLOSED EMBODIMENTS

The embodiments herein generally relate to aviary cages and, more particularly, to aviary cages having perches positioned thereon.

BACKGROUND OF THE DISCLOSED EMBODIMENTS

Aviaries are frequently used to house hens for egg production and include aviary cages therein. Generally, the aviary cage includes nesting areas where eggs are laid. The eggs are then carried from the nesting area to a collection area by an egg conveyor that is positioned adjacent the nesting area. Recently, the need to provide the hens with an area to walk around and peck and scratch has increased dramatically as more farms are producing “cage free” product. “Cage free” indicates that the hens are able to move through a much larger space than is available in conventional battery cages.

Unfortunately, providing a cage free environment requires a substantial amount of space within the aviary. In particular, a cage free environment is defined by the amount of cubic inches of space within the aviary that is available to each hen. Cage free environments therefore frequently house fewer birds than conventional aviary battery cage houses with similar footprints. For example, some aviaries have a reduced number of cage towers to accommodate the cubic inch requirements for a cage free environment. Limiting the number of hens that may be housed in an aviary results in lost profits, increased labor requirements, increased maintenance requirements, and/or increased spending for additional cages.

SUMMARY OF THE DISCLOSED EMBODIMENTS

In one embodiment, an aviary is provided having a floor and a first aviary cage including a first outside surface enclosing a first inside area. The aviary further comprises a second aviary cage substantially similar to the first aviary cage and including a second outside surface enclosing a second inside area. The second aviary cage is positioned at a height greater than a height at which the first aviary cage is positioned. An aisle extends between the first aviary cage and the second aviary cage. A first perch extends from the first outside surface of the first aviary cage and into the aisle at a first vertical distance from the floor. A second perch extends from the second outside surface of the second aviary cage and into the aisle at a second vertical distance from the floor. The first and second vertical distances from the floor are not equal.

By permitting space for the hens to move freely, the aviary 10 satisfies the requirements for the birds and their eggs to be considered cage free. See http://en.wikipedia.org/wiki/Cage-free. The hens are not continuously confined to an aviary cage. The present embodiments allow the production of eggs that may be sold under the label “cage free” because they were laid outside of a conventional cage environment. In the illustrated embodiments, the scratching floors 11 form three identical levels 17 in the aviary 10, wherein each level 17 may be accessed by a worker.

A hen may walk, peck, scratch, socialize, sleep, and lay eggs, as the bird desires in the inside area 13 and the inside area 32. These same daily activities can be carried out on the at least one scratching floor 11. The at least one aviary cage 21 may house a specific group of birds or it may be open to birds from other aviary cages 21. In an embodiment, the cage tower 18 may be configured to allow the birds to move freely up and down the cage tower 18. In an embodiment, the cage tower 18 may be configured to keep birds in the aviary segregated by vertical level. When the hens lay their eggs, the eggs may be collected in egg conveyors 28 that extend along the sides of the aviary cage 21. The egg conveyors 28 carry the eggs from the aviary cage 21 to a collection area.

Each perch 29 and each bump rail 15 provide yet other areas for the hens to utilize when they are not confined to the at least one aviary cage 21. In particular, hens may sit, hop, walk, scratch, socialize, sleep, and lay eggs from or on any perch 29 and/or any bump rail 15.

When a first perch 29A and a second perch 29B are included in an embodiment, the first vertical distance 23 and the second vertical distance 25 define a third vertical distance 27, which third vertical distance is configured to facilitate the behavior of birds to hop from one surface to another and thereby create a ladder effect between the outside surfaces 22A, 22B of the aviary cages 21A and 21B and, concomitantly, the outside surfaces 31A and 31B of the cage towers 18A and 18B.

In one embodiment, an angle formed between the first perch 29A and the second perch 29B is no greater than 45°, which configuration facilitates the behavior of birds to hop from one surface to another. In one embodiment, a plurality of first and second perches 29A and 29B are spaced apart about the outside surfaces 31A and 31B of the respective cage towers 18A and 18B. In an embodiment, each perch 29A and 29B extends into the aisle 20 to provide usable vertical space that creates additional habitable cubic inches for the birds, thereby enabling the aviary 10 to be considered cage free. In an embodiment, the first aviary cage 21A may include multiple first perches 29A, corresponding to the number of first egg conveyors 28A, and the second aviary cage 21B may include multiple second perches 29B, corresponding to the number of second egg conveyors 28B, wherein the first perches 29A and the second perches 29B are staggered in relation to each other along the first and second outside surfaces 31A, 31B of the cage towers 18A and 18B. In one embodiment, the first perches 29A and the second perches 29B are staggered vertically on the first and second outside surfaces 31A, 31B of the cage towers 18A and 18B. In one embodiment, the first perches 29A and the second perches 29B are staggered horizontally along the first and second outside surfaces 31A, 31B of the cage towers 18A and 18B.

In an illustrated embodiment, a cage tower 18C is positioned adjacent the exterior wall 16 and includes an aviary cage 21C adjacent the scratching floor 11. An egg conveyor 28C extends from an outside surface 22C of the aviary cage 21C and into the aisle 20. A perch 29C extends from the outside surface 22C of the aviary cage 21C and is positioned above the egg conveyor 28C. A perch 29D extends from the interior surface 30 of the exterior wall 16 and into the aisle 20.

In an embodiment, the perch 29C is elevated at a first vertical distance 33 from the scratching floor 11, and the perch 29D is positioned at a second vertical distance 35 from the scratching floor 11. In an embodiment, the first vertical distance 33 and the second vertical distance 35 define a third vertical distance 37, which third vertical distance 37 is configured to facilitate the behavior of birds to hop from one surface to another and thereby create a ladder effect between the aviary cage 21C and the exterior wall 16. In one embodiment, an angle formed between the perch 29C and the perch 29D is no greater than 45°, which configuration facilitates the behavior of birds to hop from one surface to another. In one embodiment, a plurality of perches 29C and 29D are spaced apart about the outside surface 31C of the cage tower 18C and on the interior surface 30 of the exterior wall 16. Each perch 29C and 29D extends into the aisle 20 to provide usable vertical space that creates additional habitable cubic inches for the birds, thereby enabling the aviary 10 to be considered cage free.

Each of the perches 29 are offset in a spaced apart arrangement to accommodate the behavior of birds to hop from one surface to another and thereby create a ladder effect on the outside surface 22 of the aviary cage 21 and, concomitantly, the outside surface 31 of the cage tower 18. In an embodiment, the perches 29 are sloped downward from the cage tower 18. In an embodiment, the perches 29 extend from the outside surface 22 parallel to the scratching floor 11. In an embodiment, the perches 29 may extend upward from the outside surface 22 relative to the cage tower 18.

The width or diameter of the perches 129A and 129B is configured to allow a hen to stand on the perches 129A and 129B.

In an embodiment, the first vertical distance 123 and the second vertical distance 125 define a third vertical distance 127. The third vertical distance 127 is configured to permit a bird to hop from the first perch 129A to the second perch 129B or vice versa.

In an embodiment, the first aviary cage 121A may include multiple first egg conveyors 128A, and the second aviary cage 121B may include multiple second egg conveyors 128B, wherein the first egg conveyors 128A and the second egg conveyors 128B are staggered vertically relative to each other along the first and second outside surfaces 131A, 131B of the cage towers 118A and 118B. In an embodiment, the first aviary cage 121A may include multiple first perches 129A, and the second aviary cage 121B may include multiple second perches 129B, wherein the first perches 129A and the second perches 129B are staggered vertically relative to each other along the first and second outside surfaces 122A, 122B of the aviary cages 121A and 121B.

Each perch 129 and each bump rail 115 provide yet other areas for the hens to utilize when they are not confined to the at least one aviary cage 121. In particular, hens may sit, hop, walk, scratch, socialize, sleep, and lay eggs from or on any perch 129 and/or any bump rail 115.

When a first perch 129A and a second perch 129B are included in an embodiment, the first vertical distance 123 and the second vertical distance 125 define a third vertical distance 127, which third vertical distance is configured to facilitate the behavior of birds to hop from one surface to another and thereby create a ladder effect between the outside surfaces 122A, 122B of the aviary cages 121A and 121B and, concomitantly, the outside surfaces 131A and 131B of the cage towers 118A and 118B.

In one embodiment, an angle formed between the first perch 129A and the second perch 129B is no greater than 45°, which configuration facilitates the behavior of birds to hop from one surface to another. In one embodiment, a plurality of first and second perches 129A and 129B are spaced apart about the outside surfaces 131A and 131B of the respective cage towers 118A and 118B. In an embodiment, each perch 129A and 129B extends into the aisle 120 to provide usable vertical space that creates additional habitable cubic inches for the birds, thereby enabling the aviary 110 to be considered cage free. In an embodiment, the first aviary cage 121A may include multiple first perches 129A, corresponding to the number of first egg conveyors 128A, and the second aviary cage 121B may include multiple second perches 129B, corresponding to the number of second egg conveyors 128B, wherein the first perches 129A and the second perches 129B are staggered vertically along the first and second outside surfaces 131A, 131B of the cage towers 118A and 118B.

At least one belt 136 extends through each aviary cage 121 to remove a deposit from at least part of the aviary cage 121. A deposit may include, but is not limited to, one or more items such as manure, an egg, litter, feathers, feed, or a dead bird. In one embodiment, the belt 136 extends through each aviary cage 121 along the length of the cage tower 118. In one embodiment, the belt 136 extends approximately 400 feet along the length of each cage tower 118. In one embodiment, the belt 136 carries deposits from the aviary cage 121 to a collection area (not shown) positioned outside of the aviary cage 121.

A scratching floor 111 extends between the first aviary cage 121A and the second aviary cage 121B. The scratching floor 111 is oriented with respect to and positioned adjacent to a respective belt 136. In one embodiment, the scratching floor 111 is planar with the respective belt 136 from which the scratching floor 111 extends. Alternatively, the scratching floor 111 is sloped to allow deposits to move back toward the respective belt 136. When the birds scratch the scratching floor 111, they scratch much of the deposits made on the scratching floor 111 onto the belt 136. Accordingly, since it is common for birds to defecate in their scratching area, the scratching floor 111 becomes relatively self-cleaning as the hens scratch. The scratching floor 111 is configured so that the deposits are scratched back to the respective belt 136. Such configuration reduces the required frequency for cleaning of the aviary 110. Any eggs laid on the scratching floor 111 may be directed back toward the belt 136 by the scratching of the hens. These eggs are then collected from the belt 136 and removed from the belt 136.

In one embodiment, the belt 136 forms a floor of each aviary cage 121. Accordingly, the birds are allowed to move freely and walk on the belt 136.

By removing deposits, particularly manure, from at least part of each aviary cage 121, ammonia levels within the aviary 110 are significantly reduced. Additionally, the need for an individual to enter the aviary 110 and clean the aviary 110 by hand is greatly reduced. Accordingly, the present embodiments permit one person to care for 150,000 to 200,000 birds, compared with the 3-5 people per 150,000 to 200,000 birds required when known cages and aviaries are used. The present embodiments also minimize or eliminate the requirement for extreme body positions, including squatting for extended periods of time and crawling and laying on the floor while loading and unloading the cage and while gathering eggs from the cage. The present embodiments further reduce potential respiratory hazards and infection hazards to the workers. If a hen lays an egg within the inside area 113, the egg will be collected by the belt 136 and carried to an egg collection area (not shown) positioned outside of the aviary cage 121.

In one embodiment, the eggs are removed from the belt 136 through the use of an egg remover 139 positioned at the end of the belt 136. FIG. 4A shows one embodiment of an egg remover 139A. In the illustrated embodiment, the egg remover 139A includes two brushes 141 that meet at a point 143. From the point 143, each brush 141 extends toward a side 147 of the belt 136. In particular, each brush 141 extends at an angle toward a side 147 of the belt 136 in the direction of movement of the belt 136, wherein the brushes 141 extend over the full width of the belt 136. The brushes 141 rotate in a direction that moves material to at least one side 147 of the belt 136. In one embodiment, the brush 141 may be an auger-shaped brush. Additionally, in one embodiment, a finger belt (not shown) is utilized to move the eggs to a side 147 of the belt 136. In yet another embodiment, any egg conveying apparatus, including but not limited to a roller having a flange, can be utilized to move the eggs to a side 147 or both sides 147 of the belt 136.

FIG. 4B shows another embodiment of an egg remover 139B. The egg remover 139B includes a single brush 149 that extends the width of the belt 136 at an angle from one side 147 of the belt 136 to the other side 147 of the belt 136. The brush 149 rotates in a direction that moves material to the downstream end of the brush 149 with respect to the direction of movement of the belt 136. In one embodiment, the brush 149 may be an auger-shaped brush.

Each brush 141, 149 is formed from a material having a rigidity that enables the brush 141, 149 to move eggs toward at least one side 147 of the belt 136. However, the rigidity is such that the brush 141, 149 is incapable of moving deceased birds. Rather, deceased birds pass through and/or under the brush 141, 149 and are deposited at an end of the belt 136. Additionally, the brush 141, 149 is positioned above the belt 136 to enable deposits other than eggs to pass under the brush 141, 149.

In one embodiment, illustrated in FIGS. 5 and 6, at least one gate 150 is positioned along at least one belt 136 to permit deposits on the belt 136 to pass thereunder and/or therethrough and to prevent birds from traveling beyond the gate. In one embodiment, the gate 150 includes openings 152 operative to enable deposits to pass therethrough. Additionally, in one embodiment, the gate 150 includes a hinge 154 operative to rotate the gate 150 and thereby enable larger deposits, such as eggs and dead animals, to move past the gate 150. In an embodiment, an electric fence may be positioned on the gate 150 to prevent live birds from entering the gate 150. In an embodiment, an electric fence may be spaced apart from the gate 150 to prevent birds from reaching and entering the gate 150. In embodiments including at least one gate 150, birds are prevented from leaving a part of the aviary 110 while deposits are permitted to travel away from that part of the aviary 110.

The present embodiments allow the removal of freshly laid eggs from the aviary 10, 110, which eggs may be sold under the label “cage free” because they were laid outside of a nest box environment. The present embodiments also prevent eggs from becoming contaminated due to slow retrieval thereof from the scratching areas or cage floor (during which time the eggs could be infiltrated by bacteria). Some embodiments permit automated removal of deceased birds.

In one embodiment, a method of constructing an aviary 10 is provided. The method includes positioning a first aviary cage 21A adjacent to a second aviary cage 21B at a height from a scratching floor 11 that is less than a height from a scratching floor 11 of a second aviary cage 21B. Each first aviary cage 21A includes a first outside surface 22A enclosing an inside area 13A. Each second aviary cage 21B includes a second outside surface 22B enclosing an inside area 13B. An aisle 20 is extended between the first aviary cage 21A and the second aviary cage 21B. A first perch 29A is extended from the first outside surface 22A of the first aviary cage 21A and into the aisle 20 at a first vertical distance 23 from a scratching floor 11. A second perch 29B is extended from the second outside surface 22B of the second aviary cage 21B and into the aisle 20 at a second vertical distance 25 from the scratching floor 11. In an embodiment, the first vertical distance 23 and the second vertical distance 25 define a third vertical distance 27 in a spaced apart arrangement to accommodate the behavior of birds to hop from one surface to another and thereby create a ladder effect between the outside surfaces 22A, 22B of the aviary cages 21A and 21B.

Each of the first aviary cage 21A and the second aviary cage 21B may include at least one belt 136 positioned within the inside area 13A, 13B. The method further includes positioning the first perch 29A and the second perch 29B adjacent the respective belt 136. In one embodiment, the respective belt 136 forms at least one floor of each aviary cage 21A, 21B. The at least one belt 136 is configured to remove a deposit from at least part of the respective aviary cage 21A, 21B. An egg remover 139 may be positioned at an end of each belt 136 to remove eggs from the belt 136.

In an embodiment, a gate 150 is positioned in relation to each belt 136 to prevent animals from leaving the respective aviary cage 21A, 21B. The gate 150 may include openings 152 to enable debris to pass therethrough. Additionally, the gate 150 may include a hinge 154 to rotate the gate 150 and thereby enable eggs and dead animals to move past the gate.
